1分贝LSB的GaAs MMIC五位数字衰减器HMC273AMS10GE
分享资料个
The HMC273AMS10G（E） is a general purpose broadband 5-Bit positive control GaAs IC digital attenuator in a 10 lead MSOP plastic package. Covering 0.7 to 3.8 GHz， the insertion loss is typically less than 3 dB. The attenuator bit values are 1 （LSB）， 2， 4， 8， and 16 dB for a total attenuation of 31 dB. Accuracy is excellent at ±0.2 dB typical with an IIP3 of up to +46 dBm. Five bit control voltage inputs， toggled between 0 and +3 to +5 volts， are used to select each attenuation state. A single Vdd bias of +3 to +5 volts applied through an external 5K Ohm resistor is required.
